David Wood 08ed338f56 sess/cg: re-introduce split dwarf kind ... In #79570, `-Z split-dwarf-kind={none,single,split}` was replaced by `-C split-debuginfo={off,packed,unpacked}`. `-C split-debuginfo`'s packed and unpacked aren't exact parallels to single and split, respectively. On Unix, `-C split-debuginfo=packed` will put debuginfo into object files and package debuginfo into a DWARF package file (`.dwp`) and `-C split-debuginfo=unpacked` will put debuginfo into dwarf object files and won't package it. In the initial implementation of Split DWARF, split mode wrote sections which did not require relocation into a DWARF object (`.dwo`) file which was ignored by the linker and then packaged those DWARF objects into DWARF packages (`.dwp`). In single mode, sections which did not require relocation were written into object files but ignored by the linker and were not packaged. However, both split and single modes could be packaged or not, the primary difference in behaviour was where the debuginfo sections that did not require link-time relocation were written (in a DWARF object or the object file). This commit re-introduces a `-Z split-dwarf-kind` flag, which can be used to pick between split and single modes when `-C split-debuginfo` is used to enable Split DWARF (either packed or unpacked).
